Apower tool is a tool that isactuated by an additionalpower source andmechanism other than the solemanual labor used withhand tools. The most common types of power tools utiliseelectric motors.Internal combustion engines andcompressed air are also commonly used. Tools directly driven byanimal power are not generally considered power tools. Power tools can produce large amounts ofparticulate matter, includingultrafine particles. Airborne particulate matter is a Group 1carcinogen.
Power tools are used in industry, inconstruction, inrenovation, in the garden, forhousework tasks such ascooking,cleaning, andaround the house for purposes of driving (fasteners),drilling,cutting, shaping,sanding,grinding,routing,polishing, painting,metalworking,woodworking, heating and more.
Using hand and power tools to cut plastic materials during construction activities can generatemicroplastics. Airborne microplastics is a type ofparticulates. Further studies are needed "on the different types of cutting tools and their associated MP production".[1]
Power tools are classified as either stationary or portable, where portable means hand-held. Portable power tools have obvious advantages in mobility. Stationary power tools, however, often have advantages in speed and precision. A typical table saw, for instance, not only cuts faster than a regular hand saw, but the cuts are smoother, straighter, and more square than what is normally achievable with a hand-held power saw. Some stationary power tools can produce objects that cannot be made in any other way.Lathes, for example, produce truly round objects.
Stationary power tools formetalworking are usually calledmachine tools. The termmachine tool is not usually applied to stationary power tools forwoodworking, although such usage is occasionally heard, and in some cases, such asdrill presses andbench grinders, exactly the same tool is used for both woodworking and metalworking.

While hand-held power tools are helpful, they also produce large amounts ofnoise,vibrations[2] andparticulates includingultrafine particles.[3]
Airborne particulate matter is aGroup 1 carcinogen.[4] Particulates are the most harmful form (other thanultra-fines) ofair pollution[5] as they can penetrate deep into the lungs and brain from blood streams, causing health problems such asheart disease,lung disease, andpremature death.[6] There is no safe level of particulates. A 2013 study concluded that "particulate matter air pollution contributes to lung cancer incidence in Europe".[7] Worldwide, exposure to PM2.5 contributed to 4.1 million deaths from heart disease, stroke, lung cancer, chronic lung disease, and respiratory infections in 2016.[8] Overall, ambient particulate matter is one of the leading risk factor for premature death globally.[9]
Many construction tasks createdust. High dust levels are caused by one of more the following:
Examples of high dust level tasks include:
Some industry standards on the size and amount of dust emitted by power tools exist,[11][12] though it appears that they are not widely known or used globally. Knowing that dust is generated throughout the construction process and can cause serious health hazards,[13] manufacturers are now marketing power tools that are equipped withdust collectors (e.g.HEPA vacuum cleaners) or integrated water delivery system which extract the dust after emission.[14][15] However, the use of such products is still not common in most places. As of Q1 2024, petrol powered tools are banned in California.[16]
Using power tools withouthearing protection over a long period of time can put a person at risk forhearing loss. The U.S.National Institute for Occupational Safety and Health (NIOSH) has recommended that a person should not be exposed to noise at or above 85 dB, for the sake ofhearing loss prevention.[17] Most power tools, includingdrills,circular saws,belt sanders, andchainsaws, operate atsound levels above the 85 dB limit, some even reaching over 100 dB.[2] NIOSH strongly recommends wearing hearing protection while using these kinds of power tools.[18]
EarlyIndustrial Revolution-era factories had batteries of power tools driven by belts from overhead shafts. The prime power source was awater wheel or (later) a steam engine. The introduction of the electric motor (and electric distribution networks) in the 1880s made possible the self-powered stationary and portable tools we know today.[19] The global market for power tools is $33 billion (in 2016) and estimated to reach $46 billion in 2025.
Prior to the 1930s, power tools were often housed incast metal housings. The cast metal housings were heavy, contributing to repetitive use injuries, as well as conductive – often shocking the user. As Henry Ford adapted to the manufacturing needs ofWorld War II, he requested that A. H. Peterson, a tool manufacturer, create a lighter electric drill that was more portable for his assembly line workers.[20] At this point, the Hole-Shooter, a drill that weighed 5 lbs. was created by A. H. Peterson. The Peterson Company eventually went bankrupt after a devastating fire andrecession, but the company was auctioned off to A. F. Siebert,[21] a former partner in the Peterson Company, in 1924 and became theMilwaukee Electric Tool Company.[22]
In the early 1930s, companies started to experiment with housings ofthermosetting polymer plastics. In 1956, under the influence ofHans Erich Slany,Robert Bosch GmbH was one of the first companies to introduce a power tool housing made of glass filled nylon.[23]
As of 2021, an electric motor is the most popular choice to power stationary tools. Other power sources includesteam engines, direct burning of fuels and propellants, such as inpowder-actuated tools, or even natural power sources such aswind ormoving water. In the past, stationary tools were powered bywindmills, water wheels, and steam. Some museums and hobbyists still maintain and operate stationary tools powered by these older power sources. Portable electric tools may be either corded or battery-powered.Compressed air is the customary power source for nailers and paint sprayers. A few tools (calledpowder-actuated tools) are powered by explosive cartridges. Tools that run on gasoline or gasoline-oil mixes are made for outdoor use; typical examples include mostchainsaws andstring trimmers. Other tools likeblowtorches will burn their fuel externally to generate heat. Compressed air is universally used where there is a possibility of fuel or vapor ignition - such as automotive workshops. Professional level electric tools differ from DIY or 'consumer' tools by beingdouble insulated and not earthed - in fact, theymust not be earthed for safety reasons.
Different battery powered power tools often use batteries which are not compatible across brands and models. This may causevendor lock-in, and results in poorsustainability if and when either the battery, charger, or power tool component fails, resulting in potentially all having to be replaced.
Examples of battery differences include the battery technologies themselves, withnickel-metal hydride (NiMH) andnickel–cadmium batteries (Ni-Cd) being common previously,[24] but as of 2021,lithium-ion batteries have become thede facto standard for new power tools. Thevoltage is one of the most important factors for battery compatibility. In simple terms, a higher voltage rating on the tool often means that the power tool can deliver more power, with all else being equal. Using a battery with the wrong voltage rating may damage the tool, persons, or surroundings. As of 2021, 18-volt battery packs are thede facto standard in new power tools. Theampere-hour, in simple terms, tells something about how long the power tool can operate before it needs to be recharged. If comparing two batteries with the same battery technology and same voltage rating, a battery with twice the amp hour rating should last about twice as long. In practice there may however be some variations to this. Also, batteries with a higher amp hour rating in practice can also often let the power tool deliver a slightly higher peak power due to the ability to deliver a higher current.[citation needed]
Even when using the same battery technology, voltage rating and amp hour rating, the interface of batteries for power tools are often not compatible across different manufacturers, and sometimes also not even within the same brand or product line. There are examples of aftermarket adapters being made so that the user can mix and match batteries between well-known brands, but these often do not fully implement the tools battery safety and monitoring systems and the use is done at the user's own risk.
There are initiatives with the goal that the same battery can be used across products from several manufacturers, mostly those who offer special tools rather than general ones. Mainly two German companies have opened their 18V systems for others:
